The purpose of this RFT is to engage a flash butt welding (FBW) contractor; with the appropriate skills, equipment and experience in operating welding depots; to assist KiwiRail in efficiently and effectively maintaining its Woburn welding depot, noting the scale of Kiwirail’s operation.

The same contractor is also expected to provide mobile flash butt welding services to KiwiRail as and when required.

Rail replacement is on-demand, currently at the rate of track programme 40 track km per year, total 80,000m of rail @50kg/m or 4,000 tonnes per annum (plus projects). New rail is manufactured offshore to KiwiRail specification in a minimum production run of 5,000 tonnes per annum servicing up to one year's requirement.

Each 5000-tonne shipment is in 4000 x 25m lengths (1.25 tonne each) delivered to CentrePort (Wellington Port). The rail is unloaded from the ship and transferred to the Rail Weld Depot (RWD) stockpile at Kiwirail’s Woburn mechanical workshops, located in Lower Hutt.

Rail is flash butt welded into longer lengths (50m, 75m, potentially 100m strings) at the Rail Weld Depot before stockpiling and ultimate delivery to the field for installation.

The Rail Weld Depot is an outdoor facility, including a welding area, quenching station, weld grinding station and gantries to load the rails.
